# compiler-rt Library Info

# library can provide.
# CommonFunctions - The list of generic functions available.
# ArchFunctions.<arch> - The list of functions commonly available for
# 'arch'. This does not include any config specific
# functions.
#
# AvailableIn.<function> - The list of subdir keys where 'function' is
# defined.
# Determine the set of available modules.
